It seems likely that taking the vaccine, although not mandatory, will open doors to the return to “normal” life. There are a growing number of voices backing a “vaccinated only” stance with regard to day to day living. It seems that unless you are vaccinated, and can prove it, you won’t be able to fly or be allowed into countries at border checks. Pubs, restaurants, cinemas and the like are to take a similar stance and only allow those who have been vaccinated to enter.
So it looks like those not taking the vaccination could be in for a very quite year or two.
